A short thought that I'd like to expand on later, but which I'll put succinctly soon.
Right now, we're starting to see liberal Christians preparing to act as apologists for the next round of attacks on Christianity in the US - namely, penalizing and attacking Christian churches (and any organization which is Christian in both name and policy) for opposing same-sex marriage. We're going to start hearing more and more arguments like this from liberals:
"When you think about it, Christians being untaxed is really unfair. Shouldn't we render unto Caesar? That's a bible quote, you know!"
"Churches are part of society, and if you really want to be part of society you should be doing your fair share. Hell, even if this wasn't being pushed to crack down on churches that oppose gay marriage, we should DEMAND to be taxed!"
"Christians need to reclaim the public mantle of love, and people see opposition to gay marriage as hateful! We should support these laws to encourage Christians to give up hate!"
And so on, and so on.
To that, I'm going to come out with my own view on these matters: the Christian response to the SCOTUS decision should be to kick liberal Christians out of their churches.
It's a very easy line in the sand: if a person supports penalizing Christian businesses or churches for rejecting same-sex marriage, or refusing to provide service for a same-sex marriage, they should not be welcomed at a Church. In fact, they should be told to leave, and regarded as no longer a member of either that church, or the faith in general.
This is going to be called divisive by some. It is - it's a necessary dividing line. All manner of politics are things Christians can disagree over, but starting here is where the line must be. Once you support throwing the weight of the state against Christians for the crime of opposing anal sex, you're done. It makes for a reasonable enough yardstick to determine when someone has become, for all practical purposes, an ex-Christian.
Of course, I'm no clergy. I'm just one guy. But as of now, this is my own personal line in the sand: whoever gets behind these laws, this social vendetta, is no longer a Christian as far as I'm concerned. They're something else - some aberrant combination of Christianity-lite and Government.
